Grinder Pumps Your Premier Pump Choice KGX2-21 2HP Dual Seal Grinder Pump, External Start (Class 1, Div. 1, Groups C & D Hazardous Location) The KEEN PUMP KGX2-21 series centrifugal grinder pumps easily handle residential, light commercial or industrial sanitary waste, reducing it to a fine slurry. The KGX2-21 pump is designed for use in pressure sewer applications or any piping network. The KGX2-21 grinder pump retrofits into many existing competitor pump installations. The KGX2-21 pump operates with the same control panel and installation piping / rail system. The recessed vortex impeller design of the KGX2-21 grinder pump provides troublefree, non-overloading operation over the entire performance curve. The KGX2-21 pump produces capacities to 43 gpm with heads to 106 feet. The KGX2-21 series pump features: Interchangeable into Competitor Installations Dual Silicon-Carbide Shaft Seals Pressed-In Motor with Internal Overload Protection 3-Bearing Shaft Support Internal Moisture Detection Strong 2hp Motor, Dual Voltage (208/230) 120 Performance Curve Total Head (FT) 100 80 60 40 20 0 10 20 30 40 Capacity (GPM) 50
Features and Benefits 1. Watertight Cable Entrance Agency-approved, watertight strain relief cord grip with compression grommet protects outer cord jacket. Epoxy-filled inner cord cap provides anti-wicking moisture protection to the motor even if powercable is cut or damaged. 2HP Grinder Pump Dual Seal KGX2-21 2. Modular Pump Design Commonality of parts across the Keen product line minimizes the amount of parts required for servicing. Heavy-duty ASTM A48, Class 30 cast iron components. 3. Strong Motor Powerful high-torque motor for reliable pump operation. Pressed stator securely holds motor and efficiently transfers heat. Class F insulation with overload protection in oil-filled chamber for cool operation and long motor life. 1 10 4. 3-Bearing Support Motor / Pump shaft securely held with upper and lower ball bearing plus additional sleeve bearing in lower seal chamber. Long 50,000 hour B-10 bearing life. 5. Double Mechanical Seal Protection Dual silicon carbide mechanical shaft seals provide twice the moisture protection for the motor. Dual seals are housed in a secondary oil-filled seal chamber. Tougher silicon carbide seals better handle sand, grit and abrasive materials. 6. Moisture Detection Seal leak probe signals alarm in control panel for scheduled maintenance. 7. Non-Overloading Hydraulic Design The recessed centrifugal impeller allows 100% performance curve operation from shut-off to maximum flow without damage to the pump or system. The recessed vortex impeller is out of the passageway of fluid flow, eliminating concerns of blockage or wear. 3 5 2 4 6 9 8. Proven Grinder Assembly Hardened (Rockwell 56-60) stainless steel grinder assembly has 30+ years proven field experience. The reversible grinder ring and grinder impeller effectively reduce solids into a fine slurry, easily passable in a piping system without concerns of clogging. Highly efficient 16,600 cuts/second. 9. Easy Piping Connection Removable 1-1/4 NPT connection flange for simple and easy connection to discharge piping. 10. Accessories Stainless steel lifting handle included. Anti-vibration rubber mounting feet optional. 8 7 10 Your Premier Pump Choice 471E State Route 250 East. Ashland, Ohio 44805 419.207.9400 fax 419.207.8031 www.keenpump.com
